Hi Aymeric!
I justed tested on one of my proxies (kamailio 1.5) and with the default setting (120s) it closes TCP connection always after 131 seconds - strange.
If I set to 30, the connection will be closed after 41 seconds. If I set to 300, the connection will be closed after 311 seconds.
modparam("rtimer", "timer", "name=tst;interval=300;mode=1;")
Using this, my timer is called every 75 seconds ;(
My linux is a standar ovh kernel "2.6.28.4-xxxx-std-ipv4-32 #2 SMP". I already got issue with the SIP NAT module statically linked into the kernel that I couldn't remove... and once more, the kernel...
I will try another kernel after some backup.
Looks like in my case there are always 11 seconds added (maybe some other timeouts before the connection enters the "idle" state in the TCP handler).
Anyway, that does not answer the problems you are experiencing.
Right. But I'm getting closer!

Some additionnal information:
I tried several value for tcp_connection_lifetime!
tcp_connection_lifetime = 120 -> close TCP conn after 50 seconds tcp_connection_lifetime = 300 -> close TCP conn after 90 seconds tcp_connection_lifetime = 600 -> close TCP conn after 160 seconds
Do I have "tick" issue? Any idea?
Are you using a non-standard OS? kernel? hardware?
Is the clock running correct on your OS?
I think I'm close to find either a bug or an issue with my kernel?
I got a timer running a route[] for statistics computation, in case that would change something?
Is the timer route executed correctly or is it also called too often?

I'm using rtimer module: could this have an impact?

Hi Aymeric!
Kamailio does not support SIP outbound. It should close TCP connection after the timeout. The timeout can be specified with http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:1.5.x#tcp_connection...
So, do I get it right that this does not work (TCP connection closed after 50 seconds by Kamailio although the default value is 120 seconds)?
(For outbound support probably the default value should be increased).
Further, usually the lifetime should be extended to the value of the registration expiration. This can be done by using http://www.kamailio.org/docs/modules/1.5.x/registrar.html#id2477171

Are you doing that in Kamailio's TM module? Please take into account that for Kamailio next version SIP-Router TM module will be used, which has received LOT of love for TCP (i.e: non blocking).
Sorry that I missed to put the version of kamailio: I'm using branch 1.5 svnversion gives 5868M ChangeLog last line is: ===================== 2009-04-29 Kamailio v1.5.1 released =====================
Seems like you are misunderstooding me: I'm working on my SIP stacks against kamailio with no change. I'm not working "on" the tm module.
